Hi,

=20

I have a guest virtual machine attached with  BCM57414 Virtual Function .

-          When the BCM VF is owned by Linux driver "bnxt_en", I am seeing =
two Rx/Tx queues are assigned by the driver.

-          When the same device is owned by DPDK PMD "net_bnxt" , I am seei=
ng only one Rx/Tx queue is assigned and used by the PMD.=20

=20

Can someone help me in understanding the difference between the Linux drive=
r behavior and DPDK PMD behavior in determining the number of queues for th=
is specific VF ?

I am using  the DPDK version "dpdk-17.11.4".

Thanks & Regards,

Vishnu
